Also wrote a basic wedding registry that allowed people to scan our list of things we wanted and say they had purchased them, or were interested and it gave a list of others who might want to go in on a group purchase. No privacy, but it was only sent to friends. Circa 2004.

More recently, hmm... as treasurer for various choir things I've written a ton of little commandline tools which give very quick access to data and allow tracking who owes what and logging their payments into a database, and tools which generate email invoices and receipts.
